Hello! I am a Software Engineer at Luma AI, where I focus on data infrastructure for multimodal research. Previously, I was an Infrastructure Engineer at Anyscale, building reliable and performant data planes supporting Ray.

I earned my Ph.D. in Computer Engineering from UC Santa Cruz in 2025, co-advised by Prof. Heiner Litz and Prof. Chen Qian (supported by CRSS & NSF). My doctoral research centered on Distributed Storage Systems, Cloud Computing, and Quality of Service. Post my graduation, I maintain a strong research interest in multimodal long-context memory.

Previously, I received my B.E. in Computer Science (with honors) from Sichuan University in 2018, and was selected as a Computer Science Star.
